Vacuum coating and coating technology development and application of explanation

PVD (physical vapor deposition) technology in the late 1970s, began to use in improving the mechanical properties of a hard film, the film is produced with high hardness, low friction coefficient, good wear resistance and chemical stability and other advantages. Initially successful application in the field of high-speed steel cutting tools tool manufacturing caused the world's attention, the people in the development of high performance, high reliability, coating equipment, also carbide, ceramic knives in a more in-depth coatings applied research. PVD process has no adverse impact on the environment, in line with the development of modern green manufacturing.

Titanium treatment process temperature can be controlled below 150 ~ 500 ℃, so the process can be used for coating titanium substrate of a variety of materials, not only has colorful decorative effect, even more important is the use of PVD technology allows coating has excellent the physical and chemical properties, physical properties greatly enhanced surface hardness, friction coefficient and other indicators such as the matrix.
